Key Concepts

Vector Cross Product

The vector cross product is an operation on two vectors in three-dimensional space that yields a third vector perpendicular to both of the original vectors. This operation is particularly useful for determining a normal vector to a plane defined by two non-parallel vectors.

Unit Vector

A unit vector is a vector whose magnitude is exactly one. It indicates direction only and is obtained by dividing any non-zero vector by its magnitude. Unit vectors are used to standardize directions in space without considering length.

Normal Vector to a Plane

A normal vector to a plane is any vector that is perpendicular to every vector lying on that plane. In three dimensions, one can compute a normal to a plane by taking the cross product of two non-parallel vectors that lie on the plane, and then normalizing the result to create a unit normal vector.
